Liebert 195551P4 Filter
The Liebert 195551P4 filter is a MERV 11 high-efficiency pleated air filter engineered for critical environmental control in Liebert HVAC systems. Measuring exactly 29.5x28.5x4, this deep-pleat filter is a direct OEM replacement for legacy units, including the 136550P4S, ensuring a precise fit without air bypass. Designed to capture up to 85% of airborne contaminants between 3.0 and 10.0 microns, it effectively traps dust, pollen, and spores while maintaining low pressure drop across the media. For technicians servicing data centers or industrial cleanrooms, utilizing the 195551P4 air filter is essential for protecting sensitive electronics from particulate buildup and ensuring optimal thermal management. The 29.5x28.5x4 MERV 11 specification provides a significant surface area for extended service life and consistent airflow, meeting the rigorous demands of high-velocity precision cooling equipment.
Key Benefits- High Filtration Efficiency: The MERV 11 rating ensures superior capture of fine particulates to protect internal system components.
- Optimized Airflow: Engineered for low resistance, supporting peak performance in HVAC equipment without straining blower motors.
- Exact OEM Dimensions: The 29.5x28.5x4 frame provides a perfect seal in Liebert filter tracks, preventing unfiltered air bypass.
- Industrial-Grade Build: Constructed with durable pleated media and a reinforced frame to withstand high-moisture or high-velocity environments.
What is the recommended replacement frequency for the 195551P4?
In critical data center applications, technicians typically replace these filters every 3 to 6 months depending on the ambient air quality and system load to prevent restricted airflow.
Will this filter fit my specific Liebert unit?
This 29.5x28.5x4 MERV 11 filter is designed specifically for large-scale Liebert environmental control systems. Always verify the nominal size on your existing filter or consult your equipment manual for the 195551P4 part number.
Does a higher MERV rating impact system efficiency?
While the MERV 11 provides enhanced air quality, it is engineered for this specific Liebert chassis to stay within the designed static pressure limits, ensuring reliable performance.
